Flame Orb

Flame Orbs are the small ammo type used to power Heretic's Phoenix Rod. They provide the player with 1 shot (regardless of skill level), and are sometimes dropped by an Ophidian when killed, although these provide 5 shots (7 on skills 1 and 5). Maulotaurs also occasionally drop Flame Orbs that can power the Phoenix Rod for 10 shots (15 on skills 1 and 5), an amount equal to that of Inferno Orb.
